Modelling the impact of the environment on offshore wind turbine failure rates

, 2013
For offshore wind turbines to become an economical energy generation option it is vital that the impact of the offshore environment on reliability is understood.

Hub height ocean winds over the North Sea observed by the NORSEWinD LiDAR array : measuring techniques, quality control and data management [PDF]

, 2013
In the North Sea, an array of wind profiling wind lidars were deployed mainly on offshore platforms. The purpose was to observe free stream winds at hub height.

Critical review of floating support structures for offshore wind farm deployment

, 2022
Art. 012007, 11 S.Floating structures enable offshore wind power deployment at numerous deep water sites with promising wind potential where bottom-fixed systems are no longer feasible. However, the large diversity in existing floater concepts slows down

Local Birds in and around the Offshore Wind Park Egmond aan Zee (OWEZ) (T-0 & T-1)

, 2010
The Dutch consortium "NoordzeeWind" operates the first offshore wind farm in Dutch North Sea waters. The park, consisting of 36 turbines on monopiles, is located NW of IJmuiden harbour, some 8 NM off the Dutch mainland coast. Named after the nearest town

Reliability of floating foundation concepts for vertical axis wind turbines [PDF]

, 2010
Offshore wind turbines are developing at a rapid pace. By far the most common turbine configuration is the HAWT (Horizontal Axis Wind Turbine) and development of these machines is largely centered about drive train and blade issues with some work ...

Accessing offshore wind turbines for maintenance : calculating access probabilities, expected delays and the associated costs using a probabilistic approach

, 2012
There are ambitious plans in place for the expansion of offshore wind-power capacity in the EU and elsewhere. However, the cost of energy from offshore wind is much higher than that from land-based generation and anything between 15% and 30% of this cost

High-resolution CFD modelling of Lillgrund Wind farm [PDF]

, 2013
We report on a fully dynamic simulation of Vattenfall’s Lillgrund offshore Wind Farm, with a focus on the wake effects of turbines on the performance of individual turbines, and of the farm as a whole.The model uses a dynamic representation of a wind ...

Impact of swell waves on atmospheric surface turbulence: wave–turbulence decomposition methods [PDF]

Wind Energy Science
To study turbulence properties, specifically vertical momentum fluxes under swell wave conditions, I investigate the impact of waves on the power spectrum and spectral coherence of turbulent wind across various spatial and temporal scales.

Analysis of offshore wind turbine operation & maintenance using a novel time domain meteo-ocean modeling approach

, 2012
This paper presents a novel approach to repair modeling using a time domain Auto-Regressive model to represent meteo-ocean site conditions. The short term hourly correlations, medium term access windows of periods up to days and the annual distibution of
